Try to remain calm in the presence of yellowjackets. Move slowly and deliberately and gently brush the yellowjacket away if it lands on you.

Call a professional pest control operator to remove a yellowjacket nest. This is a dangerous task for an amateur.

And here are the DON’Ts…

Don't swat at yellowjackets. They are more likely to attack and sting when aggravated.

Don't smash a yellowjacket. When crushed, they give off an alarm pheromone that can cause others in the area to attack.

Don't wear perfume, scented hairspray or lotion, or brightly colored clothes if you are going outdoors. Yellowjackets are attracted to these things.

Don't let children play in overgrown or wooded areas. These are prime nesting sites for yellowjackets.

Don't use gasoline to eliminate yellowjackets. Gasoline should never be poured into underground nest holes. (This should be common sense, but you'd be surprised how many YouTube videos show people trying to kill a nest this way!)
